Come on Minecraft, you made extremely cool concepts before. Why did you choose these for the mob vote? And yes, this is sadly confirmed as they just released the crab video. Even if the other two aren't confirmed, another person has claimed that the other mobs are going to be a penguin and an armadillo. My point still stands here: this mob vote is more boring and dull compared to the other ones, whose mobs all had interesting and cool designs. This one will use real life animals as candidates.
